An Overview of Modern Applications of Negative Binomial Modelling in Ecology and Biodiversity

open access: yesDiversity, 2022
Negative binomial modelling is one of the most commonly used statistical tools for analysing count data in ecology and biodiversity research. This is not surprising given the prevalence of overdispersion (i.e., evidence that the variance is greater than ...

Non-normal Distributions Commonly Used in Health, Education, and Social Sciences: A Systematic Review

open access: yesFrontiers in Psychology, 2017
Statistical analysis is crucial for research and the choice of analytical technique should take into account the specific distribution of data. Although the data obtained from health, educational, and social sciences research are often not normally ...

Entanglement and Fisher Information for Atoms–Field System in the Presence of Negative Binomial States

open access: yesEntropy, 2022
We developed a quantum scheme of two atoms (TAs) and field initially in a negative binomial state (NBS). We displayed and discussed the physical implications of the obtained results in terms of the physical parameters of the model.

Stein factors for negative binomial approximation in Wasserstein distance [PDF]

open access: yes, 2015
The paper gives the bounds on the solutions to a Stein equation for the negative binomial distribution that are needed for approximation in terms of the Wasserstein metric.

Distinguishing Between Binomial, Hypergeometric and Negative Binomial Distributions [PDF]

open access: yesJournal of Statistics Education, 2013
Recognizing the differences between three discrete distributions (Binomial, Hypergeometric and Negative Binomial) can be challenging for students. We present an activity designed to help students differentiate among these distributions. In addition, we present assessment results in the form of pre- and post-tests that were designed to assess the ...

Analysis of generalized negative binomial distributions attached to hyperbolic Landau levels

open access: yes, 2016
To each hyperbolic Landau level of the Poincar\'e disc is attached a generalized negative binomial distribution. In this paper, we compute the moment generating function of this distribution and supply its decomposition as a perturbation of the negative ...

A Poisson Mixed Model with Nonnormal Random Effect Distribution

open access: yes, 2011
We propose in this paper a random intercept Poisson model in which the random effect distribution is assumed to follow a generalized log-gamma (GLG) distribution.

Group sequential designs for negative binomial outcomes

open access: yes, 2018
Count data and recurrent events in clinical trials, such as the number of lesions in magnetic resonance imaging in multiple sclerosis, the number of relapses in multiple sclerosis, the number of hospitalizations in heart failure, and the number of ...

Goodness-of-Fit Test for the Bivariate Negative Binomial Distribution

open access: yesAxioms
When modeling real-world data, we face the challenge of determining which probability distribution best represents the data. To address this intricate problem, we rely on goodness-of-fit tests.

New bounds on Poisson approximation to the distribution of a sum of negative binomial random variables [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2018
The Stein-Chen method is usedto give new bounds, non-uniform bounds, for the distances between the distribution of a sum of independent negative binomial random variables and a Poisson distribution with mean, where ri and pi = 1-qi are parameters of ...
